When Vanheden and Dynamit-Harry tries to break doctor Busé out of jail, they get Herman Melvin instead. He has been working at the Swedish Mint and the doctor, who has started to think like Sickan, has written a plan for making a burglary there, on Melvin's back. However, something goes wrong. They don't get a lot of Deutsch-marks as they planned but instead, they end up on a ship going to Poland, together with bunches and bunches of Polish Zlotys (the Polish currency). In Poland, they discover that the mafia are very interested in that money and Wall-Enberg is working with the mafia.
